Test Framework Layers

• Test Classes: Java classes under src/test/java/com/example/tests/ that contain test methods using Selenium WebDriver.
• Page Objects: Java classes representing web pages under src/main/java/com/example/app/pages/ implementing the Page Object Model.
• Test Data: JSON files stored in src/test/resources/testdata/ holding input data for tests.
• Utilities: Helper classes for reading JSON files and parsing data, e.g., JsonUtils.java.
• Configuration: Properties files or environment variables to manage URLs, browsers, credentials.

Configuration Patterns

• Environment Config: Use config.properties or system properties to set base URLs and environment (dev, test, prod).
• Browser Selection: Pass browser type as a Maven parameter or environment variable to run tests on different browsers.
• Credentials: Store sensitive data encrypted or use environment variables; do not hardcode in JSON or code.
• JSON Test Data: Load JSON files from src/test/resources/testdata/ using utility methods before test execution.

Test Reporting and CI/CD Integration

• Use TestNG or JUnit reports for test execution results.
• Integrate with Maven Surefire plugin to generate XML and HTML reports.
• Use Jenkins or GitHub Actions to run tests automatically on code commits.
• Publish reports and logs for easy review of test outcomes.

Best Practices

• Separate Test Data: Keep JSON test data outside code to allow easy updates without recompiling.
• Use Page Object Model: Encapsulate page elements and actions to keep tests clean and maintainable.
• Utility Methods: Create reusable methods to read and parse JSON data safely and efficiently.
• Parameterize Tests: Use data-driven testing with JSON to run tests with multiple data sets.
• Secure Sensitive Data: Avoid storing passwords or secrets in plain JSON files.

Self Check

Where in this folder structure would you add a new JSON file to store test data for the "Registration" feature?

Key Result

Store JSON test data in src/test/resources/testdata and load it via utility classes for data-driven Selenium tests.
